Vapor phase alkylation of 1-naphthol withmethanol over Ni-Co ferrites
Vapor phase alkylation of 1-naphthol with methanol has been carried out over Ni1-XCoXFe2O4 (x = 0.0, 0.50, 0.75, 1.0) type ferrospinels prepared via. low temperature co-precipitation method in a down flow fixed bed reactor. 2- Methyl-1-naphthol was found to be the major product. The activity of the catalysts was varied with acidity of the ferrospinels systems studied. It was observed that system possessing higher ‘x’ values were highly selective for 2- methyl-1-naphthol. The maximum yield of 59.6% with 84.5% selectivity of 2-methyl-1-naphthol was obtained under optimized conditions of temperature 573 K, methanol to 1-naphhthol molar ratio 3:1 and WHSV 0.4 h-1.
